Glass catfish

[jsantii12]

Hey everyone, I have two tanks, but the one I am referring to is my 20g and it’s running on an aqueon quiet flow 30. I’ve had my tank set up for like 5 months. Anyways, I have glass catfish, 3 tetras, 2 Cory. Well I bought 3 more glass from my local store and maybe I didn’t notice while one was in the bank but I noticed it later that night and he has a curve to him. I read up about it and read it can be an injury, disease, or tb. My numbers have been reading very well in my tank. No spikes after adding and it’s been 2 days going on 3. He swims fine, goes to the top, goes to the bottom, eats well, etc. Any suggestions?!

Curved spine could be nutritional or even age related.
Many disease present with curved spine besides TB or columnaris.
Usually the disease is too far along by the time this symptom presents.
If the curve gets worse I would remove to Hospital tank or euthanize...
